The copper plates out while the zinc dissolves, leaving a transparent zinc sulphate solution.
When a iron nail is dipped into copper sulphate solution after sometime the colour is changed into pale green.
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
The iron is a more active metal than copper, so the iron atoms in the nail replace the copper atoms in the copper sulphate solution, so it becomes iron sulfate. The copper atoms will start to build on the iron nail, as well.
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Zinc is a silver/grey coating.
It isn't displaced as gold is less reactive than copper sulphate!
no reaction would take place
Zinc is higher than copper in the electrochemical series, so it will displace copper from it's solutions.Zn + CuSO4 = ZnSO4 + CuCopper plates onto the zinc as a small amount of zinc sulphate is produced.
This is due to something called a displacment reaction, during a displacment reaction one of the particals from one of the substances "swap" with another partical from the solution In the case of zink and copper sulphate solution, the copper and zink 'switch places to produce copper and a solution of zink sulphate. This is how, A + BC = B +AC
